A key reaction in the synthesis of silicone polymers is the addition of a silicon compound containing a Si-H group to a C=C double bond. The main industrial catalysts for these reactions are Pt compounds that suffer from the formation of various by-products, as well as deactivation of the catalysts to form colloidal Pt that discolors the final products. Markó et al. (p. 204) now report on a highly active and selective Pt-carbene catalyst that suppresses both of these unwanted effects.
